Comparative Study on the External Grind-Hardening Experiments of 40Cr Steel and 45 Steel

Abstract:

A new manufacturing technology, external grind-hardening, is put forward and orthogonal tests are carried out with 3-level 3-factor aimming at 40Cr steel and 45 steel. A certain depth of Martensite layer is found on the hardened surfaces of both materials by metallographic observation and the hardness values meet the design requirement, which demonstrates the practicability of the new technology. Orthogonal analysis is proceeded successively for the acquirements of influencing pattern and significance of factors, and comparative study is carried on the hardening effect and feature for the both materials.
